IMPROVEMENT IN HERMETICALLY-CLOSING JAR-COVERS.

Specification forming part of Letters Patent No. 190,940, dated May15,1877; application filed March 31, 1877.

To all whom it may concern Be it known that I, THEODORE A. WEBER, of thecity, county, and State of New York, have invented aHermetically-Olosing Jar- Gover, of which the following is aspecification The object of my invention is to close the opening of jarshermetically, whichI do by pressing a rubber ring against the topsurface of the jar-mouth by means of two eccentricshaped levers pivotedto a metal cap.

Figure 1 ot' the accompanying drawing shows the cover in the closingposition, while Fig. 2 shows the position in which the cover can beremoved from the jar. Fig.3 is a sectional view of the arrangement, andshows the metal cap A, with its two downward-reaching ends, to which thetwo eccentric levers E E are pivoted at G G, the wire F connecting thetwo levers E E at L L, while the other eccentric-shaped ends of thelevers E E are acting against the under part of the jar-rim B, pressingthe cap A against the glass disk D, and this disk the rubber ring 0against the top of the rim B, and so holding the jar hermetically closedtill the eccentric edges H H of levers E E are withdrawn from thejar-rim, and the cover is removed from the jar-mouth.

I claim as my invention The combination of cap A with attached eccentriclevers E E, acting against jar-rim B, to press the rubber ring 0 tightlyagainst the top surface of the jar-mouth, as and for the purposespecified.

THEODORE A. WEBER.
